The new LPC845 breakout board has 3 onboard LEDs- Red, Green, and Blue. The brightness of these LEDs can be controlled using a PWM signal by changing the duty cycle values for each of them. As this board has an SDK support, I have used the SDK drivers to implement this application. 

NXP has released the newest versions of MCUXpresso SDK, IDE, and configuration tools. In addition to new product support, you will find these updates and enhanced features in the new releases:

MCUXpresso SDK v2.5.0

• Updated support for i.MX RT1020, i.MX RT1060, i.MX7ULP, i.MX8MQ, LPC54S0xx, LPC51U68
• Updated to latest GNU Arm Embedded Toolchain compiler (GCC Version 7-2018-q2-update)
• Expanded device and board support for Azure Cloud Connectivity, MCU Bootloader, NXP Touch Library, Multicore SDK
• Updated included middleware - mbedTLS, Amazon FreeRTOS(TM), emWin
• Updates to NXP developed middleware and drivers:
  • SDMMC, SDIO, SDSPI
  • EDMA, Flash, FlexCAN, FTM, SAI, GPIO

We are pleased to announce that MCUXpresso Config Tools v5 are now available.

MCUXpresso Configuration Tools is a product with set of tools that help users of all levels with a Cortex-M-based MCU solution.

We are pleased to announce that MCUXpresso IDE v10.3.0 (build 2200) is now available.

This is a major new version of the IDE, and contains many new features and enhancements over the previous v10.2.1 and earlier releases. The attached presentation, recommended viewing for all users (new or experienced), provides an overview of many of the major changes, as well as things to be aware of when upgrading from an earlier release

U-Boot banner is printed in makefile of u-boot. If you edit following lines, and execute updated u-boot , you can see desired banner.

$(VERSION_FILE):

                                 printf ' #define U_BOOT_VERSION "YOUR STRING" ' \

                                    "$(U_BOOT_VERSION)"

Also, you can edit version, patch level, sublevel and extraversion field of u-boot which are defined at the top of makefile.

I have an experience with execute u-boot standalone application on P2041RDB. Standalone addres (CONFIG_STANDALONE_LOAD_ADDR) is given 0x40000 as default. This configuration is in ./arch/powerpc/config.mk in my model. I don't why, I cannot execute simple hello_world application following commands which locates ./examples/standalone/hello_world.c

1. tftp 40000 hello_world.bin

    go 40000 

2.  tftp 40000 hello_world.elf

     bootelf -p 40000 

Both of them gives illegal insturction error.

Then, I update standalone address to 0x23000. Following command works now!

 tftp 23000 hello_world.bin

go 23000

But still, bootelf command does not work..

Maybe, you have experienced this problem.. I wish this guide helps you!

To configure trustzone feature for mcuxpresso IDE, you need to add cc-flags and ld-flags like this...

The SDK Generator Docs have been uploaded, here is the link SDK Generator Docs.

I have to say that the work is still on-going, 60% done. The outline is set and finished parts are all updated.

We have added CMSIS Device Family Pack generator as a part of SDK generator, it is integrated into release/2.5.0_rel9_rfp branch.

How to Uboot...  I thought I would write this up as many developers using Layerscape, QoriQ and Qonverge devices will start with a boot loader as the first access to their own newly minted hardware.  There are two paths here.  The first is to get our SDK and find the uboot source in that, modify it as needed.  This is time consuming as you need to build an image to have Yocto pull the source code, and you need to jump through some hoops to rebuild with yocto after making your own custom uboot. 

The second is to go straight to the git repo, pull it and build with the cross compiler toolchain that seems most appropriate.  This can be easier in general...  To do this:

When you start a board bring up activity from scratch, there are many challenges. The first of these challenges is the choice of the development environment. Is there any commercial agreement with an IDE Vendor? How flexible is debugging on the IDE and build time, code footprint after optimization etc are related concerns. If the choice is a command line based build environment, the developer is free to choose what features he needs and how easily he can customize it for his requirements.

In case of a Graphical development environment, the IDE takes that decision for you. There are many Graphical IDEs some are commercially licensed and some are available with opensource licenses. Eclipse based IDEs are very famous across the opensource licensed Graphical IDEs.

New release version v1.0.1

Please find attached a document detailing various features related to using the iMXRT1020-EVK evaluation board with MCUXpresso IDE v10.2.1 and SDK v2.4.

This updated v1.0.1 version comes to fix a reported typo (Documentation Error Report ) on the SDRAM base address value. See the Revision History section on the first page of the document for details.

The following article explains how to use the MCUXpresso Software and Tools to enable runtime statistics for Amazon FreeRTOS V10

We are pleased to announce that MCUXpresso IDE v10.2.1 (build 795) is now available.

This is a maintenance release that builds upon the previous MCUXpresso IDE v10.2.0 release, and we recommend that all existing users download and install this new version.

Hi community

For some time now we have based our product developments on Kinetis devices and uTasker and are very pleased with the simplicity and reliability that results (as well as Mark's personal support).   One of our main product development requirements was to eliminate custom host USB drivers.  Having end users install drivers is a support headache and we wanted as much plug and play as possible  With utakser, we've been using the following: 

• USB Flash driver, 
• USB Keyboard interface and 
• USB serial interface.

The Kinetis Design Studio support has been phased out. The latest SDK version 2.4 doesn’t support this toolchain. The SDK builder always builds new SDK packages from the latest SDK version supporting the selected device/board/kit. That is the reason why KDS is not on the list of the available toolchains now.

Attached is a sample source code for OTP programming in NXP LPC54018 MCU.

Brief about the example:

The example programs 4 words of data each into OTP bank 1 and OTP bank 2. The example uses LPC54018 SDK drivers. The complete SDK for LPC54018 can be downloaded from Welcome | MCUXpresso SDK Builder .

I was surprised to learn MQX(Ver 4.2) does not support SPI Slave configuration.

Reference

There are many workarounds in the community but the information is in bits and pieces. So i decided to write this note.

I wanted to configure SPI0 Channel on MK64FX512VLQ12 board as Slave driven by interrupt in which can call MQX APIs. I have MQX Ver 4.2 installed.  My base BSP is derived from TWR-K64 board BSP given by MQX. IDE is KDS.f Reference hardware is TWR-K64 board.

I have the OM13086 Cloud Connectivity Kit
I have been following the ZentriOS "Quickstart Guide".
As part of the Zentri OS Quickstart procedures, I chose "Custom Install", so instead of using the "Zentri IDE", I'm uisng LPCXpresso 8.2.2, with the Zentri SDK plugin

We are pleased to announce that MCUXpresso IDE v10.1.0 (build 589) is now available.

This incorporates many new features, as well as enhancements based on feedback that we have received since the original MCUXpresso IDE v10.0.0 launch back in March.
